SIPHON MECHANISM FOR WATER=CLOSETS.

This valve may dent of Brooklyn, Kings county, State of be of any suitable or ordinary construction, New York, have invented certain new and but is preferably carried by a valve stem h 5 useful Improvements in Siphon Mechanism working in a bracket it carried by the long for Water-Closets, of which the following is leg of the siphon and operated by means of a specification. a suitable connecting rod h and lever h My invention relates to siphon mechanism The cistern or tank within which the siphon for water closets, and has for its object to mechanism is contained is provided with a 1o produce a device which will operate to refill suitable refilling cock of ordinary or prethe bowl after use after the siphon has been ferred construction, preferably a ball-cock. kG The operation of my device is as follows: To this end my invention consists in pro- The main or starting valve II, when lifted by yiding a means for producing an after-fill in a proper pull, starts the flow, and after the 15 the bowl, the same being controlled by a main valve is reseated the siphon will convalve, and providing a connection between tinue to discharge into the water closet basin the after-fill valve and the air inlet valve. until the sliding float G on the rodg, which In the drawings forming part hereofFigconnects the air valve 0 with the after-fill ure 1 is a sectional elevation of a water closet valve d, descends against the stop g on the 2o siphon mechanism embodying my invention. said rod andtherebyopens both thelastnamed Fig.2isan elevation thereofshowing the opervalves.

which case only the movement ofv the float with the rod will be utilized for the purpose of closing.

In order to increase the efficiency of the apparatus I may enlarge or expand the upper bend. of the siphon pipe. It will be observed by referring to Fig. 3 that this enlargement or expansion has been accomplished by flattening or laterally expanding the pipe. This flattening or lateral expansion I believe to be most efficient, in that the upper bend is brought down lower than it would be were it not flattened out. Hence the water in the tank or cistern need not rise so high as it would were the bend of the siphon not thus flattened or laterally extended.

I desire it to be understood that I do not specifically limit myself to the precise structure shown, but the same may be departed from in structural particulars without departing from the spirit of my invention.

WhatI claim, and desire to secure by Letters Patent, is-

1. In a water closet flushing apparatus, the combination of a siphon provided with a refilling valve, an air inlet valve, a connection between the refilling valveand the air inlet valve, the said connection being provided with a float for operating the same and movable respectively to the connection.

2. In a water closet flushing apparatus, the combination of a siphon provided with a refilling valve and an airinlet valve, operating -mechanism for each of said valves, and a rod connecting the operating mechanisms of the valves, and a sliding float on the rod, substantially as described.

3. In a water closet flushing apparatus, the combination of a siphon provided with a refilling valve and an air inlet valve, operating mechanism for each of said valves, and a rod connecting the operating mechanisms of the Valves, a slide float on the rod, and adjustable stops upon the rod against which the sliding float acts, substantially as described.
